Yes, but this would be another patch and it is a bit more work since
you have to test the clang support.
Is building with clang already supported? I'm curious since this is
something I'd like to test locally too but neither code nor tickets give
me any hope on it. Hence asking directly.
There is some support to build with clang, but I guess this is not
regularly tested/used. You can test it with:
[riscv/rv64imafdc]
COMPILER = clang
However, this quickly fails with:

You still need Newlib somehow and also the compiler-rt library for your
target.
